There would be terror to hit Moab, like the terror of the apocalypse judgment day of Isaiah, chapter 24. Terror was all around with pits and snares to catch people. If they fled, they would fall into a pit. Even if they crawled out of the pit, they would be caught in a trap. There was no escape. They tried to flee to Heshbon, the capital of Ammon, the country north of Moab. However, they were surprised to learn that Heshbon was also on fire. This was the capital city of King Sihon, or house of Sihon, dating back to the days of Joshua, chapter 21. The Moabites would have problems with their foreheads and scalps. They would be cursed, and then perish. The people with their god Chemosh would lose their sons and daughters to captivity.
